, To (11 whom, it may concern.-

Be it known that I, KASIIO TsUJr, a subject of the Emperor of Japan, and a resident process of their manufacture.

It is Well known that when cement is brought in contact with moisture its crystalline formation is broken up, and this chemical change causes the cement, when afterward used,to set more slowly; and the object of my invention is to bring the cement when in its crystalline condition into intimate contact with moisture, the amount of moisture being regulated to effect the efllorescence of the cement in a rapid and economical manner and to the desired extent.

With this object in view my invention consists of certain constructions and combination of parts, the preferred form of which will be first specifically described and then the nature and scope of the invention particularly pointed out in the claims; I In the drawings and specification accompan ing this application I have for the sake of i1 ustration shown and described a machine embodying my invention in its preferred form. Idesire to have it understood, however, that the particular construction shown and described is merely for the purpose of illustrating my invention, and many changes can be made in the form, construction, and arrangement of parts without departing from the spirit thereof. U

Referring to the drawings, wherein the same part is designated by the same reference-numeral wherever it occurs, Figure 1 is a side elevation of the preferred form of my invention, a part ofthe drum being broken away for convenience. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a view similar to Fig. 1, parts, however, being shown in central longitudinal section. Fig. 4 is a crosssection of the drum'or cylinder. I side elevation, partly in section, of the device by which moisture is supplied by the drum. Fi 6 is a top plan View of the construction s own in Fig. 5. Fig. 7 is an end view of Fig. 5 ,partly broken away. Fig. 8 is Fig. 5 is aa side elevation of the filtering device by which the dust carried out of the cylinder by the air is collected. Fig. 9 is a view, partly in section, of Fig. 8, the section being taken at right angles to Fig. 8. Fig. 10 is a top plan view of the construction shown in Fig. 8, partly broken away. Fig. 11 is a detailed View of one of the filter-frames.

1 designates a cylinder or drum provided with supporting-rings 2,which run on rollers 3, supported by suitable beds 4.

5 is a worm-gear secured around the cylinder, and 6 is a worm carried on the shaft 7 in engagement with the gear 5. The shaft 7- is suitably driven and by its rotation rotates the drum 1.

Located on the interior of the drum are a series of shelves 8, which are arranged substantially radially of the drum and extend longitudinally thereof. These shelves in the rotation of the drum pick up material in the drum and carry it up and drop it.

9 represents a series of plates which are located between the shelves 8, with their faces arranged at an angle to the axis of rotation. These plates, as will be seen from Fig. 3, form a kind of interrupted screw through the cylinder and upon the rotation of the cylinder will cause material in the cylinder to be fed therethrough. 1

10 is a stationary plate provided with a shoulder 11, the shouldered portion of the plate extending into the drum and closing one end thereof. Through this plate extends the pipe 12, by means of which material is fed into the drum and the pipe 13, the' other i end of which extends to the filter, which wil be hereinafter described. 14 is aplate similar to the late 10 and closing the delivery end of the rum. The plate 14 is provided with an opening 15 near its bottom, from which extends the pipe 16, connected with the air-moistening apparatus .17.- The pipe 16 has located in its lower portion the delivery-pipe 18, by which the material after being treated is delivered from the drum. The moistening-box 17 consists of a substantially rectangular box, as is shown in Figs. 3 5, 6, and 7, provided at its top with a mouth 18, in which is mounted the sliding plate 19 for controlling the opening in the mouth 18. i

' 20 is a partition which'cxtends through the box and divides the box into two parts. This partition at its upper portion 21 is made I solid, whereas its lower portion 22 is a form of a screen composed of wire-gauze or the like.

23 is a pipe connected to a suitable source of steam-supply, the steam being controlled 'by a valve 24.

25 is a pipe extending into a tank 26, the pipe 25 being provided with a controllingvalve 27 The pipe 23 is provided on its interior with a nozzle 28 adjacent to the pipe 25, which is also provided with a nozzle 29, as is shown in Fig. 5. These two nozzles are arranged in the position shown in Fig. 5, forming-an injector, whereby steam issuing from the nozzle 28 and passing over the nozzle 29 will draw water from the tank 26 and cause the water I and steam to mix in the pipe 23.

ture to the air admitted through the mouth 18, the valve 27 is opened, which allows water to be sucked up from the tank 26 and to be mixed with the steam and pass into the box 17. The network or screen 22 will stop the water carried by the steam which is not sufficiently broken up. 30 is a pi peby which this water may be drawn out. The-moisture-laden air passes through the box 17, through the pipe 16, and into the drum,

. where it comes in contact with the cement or other material which has b een'fed into the drum. The shelves 8 operate to pick the material in the drum up and drop it, breaking up the mass of materialand at the same time allow the moisture in the air to'reach all parts of the mass. The projections 9 'act at the same time to feed the material through the drum until it passes into the pipe 16 and out of the delivery-pi e 18. The moisture- ,laden air in passing t ou'gh the drum' picks up and carries away a large amount of valuable dust, and in order to recover the dust I connect to the pipe 13 a filtering device 31. The form of'the filter shown consists of a casing provided in its bottom with a suitable opening 32, through which the pipe 13 is'connected. 33 is a partition arranged transversely to the casing and near the upper end. Suspended from the partition 33 arefilterframes 34. One of these filter frames is shown in crosssection in' Fig. 1 1 and consists of a wedge-shaped frame 35, formed of wood or similar material, around which is wrapped cloth 36. The bottom of these frames is also covered with cloth, as at 37, while the top of the frame is left open.. These frames are into the delivery end of the drum.

separate from each other and are held in po= I sition by the hoops 38. The partition 33 is provided with a series of openings 39, which coincide with the tops of the filter-frames, as is shown in Fig. 10. In order to cause the air to pass through the drum and filter-frames, Iprovide the filter with a pair of projections 40, in which are mounted the rotary fans 41, mounted on the shaft 42 and provided with the pulley 43, which may be driven in any suitable manner. The air drawn from the drum by the fans is thus caused to pass through cloth surrounding the filter-frames, where the dust carried by the air is left, and then out through the openings in theprojection 40.

The'construction and operation of my apparatus is such that the amount of moisture delivered to thematerial in the drum can be regulated. By regulating the speed of rotation of the drum the rate of movement of material through the drum 'can be regulated, and by regulating the opening in the box 17, the supply of steam, and the speedof'the fans the amount of air passing through the drum can-be regulated. From this it will be seen that the material in the drum, such as ce- -ment, can be caused to receive the desired amount of moisturev to effect the desired amount of eflloresce'nce of the material.

What I claim as-new, and desire to secure by Letters Patent, is I 1.
